Nanostraws sample a cell's contents without damage

Cells within our bodies divide and change over time, with thousands of chemical reactions occurring within each cell daily. This makes it difficult for scientists to understand what's happening inside. Now, tiny nanostraws developed by Stanford researchers offer a method of sampling cell contents without disrupting its natural processes.

Breakthrough in understanding heat transport with a chain of gold atoms

The precise control of electron transport in microelectronics makes complex logic circuits possible that are in daily use in smartphones and laptops. Heat transport is of similar fundamental importance and its control is for instance necessary to efficiently cool the ever smaller chips. An international team including theoretical physicists from Konstanz, Junior Professor Fabian Pauly and Professor Peter Nielaba and their staff, has achieved a real breakthrough in better understanding heat transport at the nanoscale. The team used a system that experimentalists in nanoscience can nowadays realize quite routinely and keeps serving as the "fruit fly" for breakthrough discoveries: a chain of gold atoms. They used it to demonstrate the quantization of the electronic part of the thermal conductance. The study also shows that the Wiedemann-Franz law, a relation from classical physics, remains valid down to the atomic level. The results were published in the scientific journal Science on 16 February 2017.

New, ultra-flexible probes form reliable, scar-free integration with the brain

Engineering researchers at The University of Texas at Austin have designed ultra-flexible, nanoelectronic thread (NET) brain probes that can achieve more reliable long-term neural recording than existing probes and don't elicit scar formation when implanted. The researchers described their findings in a research article published on Feb. 15 in Science Advances.

Nanotechnology based gene editing to eradicate HIV brain reservoir in drug abusers

Opiate abuse is a significant risk factor for HIV infection, and in combination they can have a devastating effect on the brain. Scientists at FIU Herbert Wertheim College of Medicine (HWCOM) are studying new therapies that can short-circuit HIV infection and mitigate the damaging effects that opiate addiction has on the central nervous system.

Making sodium-ion batteries that last

Lithium-ion batteries have become essential in everyday technology. But these power sources can explode under certain circumstances and are not ideal for grid-scale energy storage. Sodium-ion batteries are potentially a safer and less expensive alternative, but current versions don't last long enough yet for practical use. Now, scientists have developed an anode material that enables sodium-ion batteries to perform at high capacity over hundreds of cycles, according to their report in the journal ACS Nano.
